Answer:
27 times bigger
Step-by-step explanation:
V(sphere) = 4/3πr³
Michael: 4/3π3³ = 4/3×27π or 36π
Patrick: 4/3πr³ = 4/3πx9³ or 4/3x729π or 972π
36π to 972π is 1 : 27
Answer:
Wanda and Dave will catch each other in 54 seconds after Dave starts walking.
Step-by-step explanation:
Let Wanda and Dave catch each other when x be the time after Dave starts walking and y be the distance covered by them
It is given that Wanda started walking along a path 27 seconds before Dave and the constant speed of Wanda is 3 feet per second.



.... (1)
The constant speed of Dave is 4.5 feet per second.

.... (2)
Equate equation (1) and (2).


Divide both sides by 1.5.


Therefore, Wanda and Dave will catch each other in 54 seconds after Dave starts walking.

Answer:
3/8
Step-by-step explanation:
Let the missing fraction be x
So, 1/2+x =7/8
To find x, we take 1/2 to the rhs and 1/2 turns to -1/2
x = 7/8-(1/2)
Taking LCM as 8...
We can convert 1/2 to 4/8
Therefore,
x = 7/8 - 4/8
= (7-4)/8
=3/8
